Weather Radar in Lincoln to be upgraded
Local radar services will be disrupted temporarily

[July 14, 2017]  LINCOLN - The weather radar (WSR-88D) used by the National Weather Service Forecast Office in Lincoln, Illinois will be down for three to four days, beginning Monday July 17, 2017, for technicians to install an important technological upgrade. The work on the WSR-88D has been scheduled to minimize any potential impacts to office operations and will be delayed if hazardous weather is forecast.

During the outage, radar coverage is available from adjacent radar sites including Chicago/ Romeoville IL, Davenport IA, St. Louis MO, Paducah KY, Evansville IN and Indianapolis IN.

A crew will install a new signal processor, which replaces obsolete technology, improves processing speed and data quality, provides added functionality, and increases IT security.

This is the first of four major upgrades, known as service life extension projects (SLEP), planned in the next five years to replace and refurbish major components of the 20 year old WSR-88Ds and to keep the radars operational into the 2030s.

The $150 million investment is being made by the three organizations that use these radars, the NOAA National Weather Service, United States Air Force and Federal Aviation Administration. The three other service life extension projects include refurbishing the transmitter, pedestal, and equipment shelters.

The tri-agency Radar Operations Center, which supports the radars, estimates the project will be completed by early November 2017 to upgrade the signal processor on all 159 operational WSR-88Ds.
